T0 aZZ w7wm it mag concern:

130 it known that we JOHN WVESLEY EMERT andRo:nm1vr I-IILL, 01" J ohnstown, in the county 0f Omnb1ia and Stute 0f Pennsylvania, have 5 invented certai 11 new and useful Improvements in Gar-Ventilators; and we hereby dec]are the following 130 be a fu1l, c1ear, and exact description of Ehe invention, such as will enable others skilled in the ELFE 130 which 10 it pertains to make and use it, reference be- 1'1'1g had t0 the accompanying drzuvings,which f0111'1 art; 0f this specification.

Our invention relates t0 an improvement in ventilaters 1"01 cars; and 113 consists in the 15 combination 01" a suit@ble frzune with a pivoted double h0od, which is operated entire1y by the pressure 0f Ehe air Horn Ehe direetion in which the ears are moving, as Will be m0re fully described hereinafter.

The objecb 0f 0ur invention is t0 so coustruct a h0od thab 113 will catch the air in whichever direction the car 1's m0ving and f01ee it; directly 1'11t0 th0 cm, an(l thus ke0p the Gibt always supplied with pure air.

Figures 1 und 2 are elevations 0f 0111 ventilatot, Unken at 1ight angle t0 euch other.

A represents the side 0f the 0er, upon which the tw0 Standards of the fra1ne B 2L1'0 seeurely bo1te(l npon opposite sides 0f the ventilating hole 01 wiudow. These two frmnes 01 stand ards B Will be made entirely separate fr0m ea0h 0ther und connected together by a cross bar 01. piec0, O.

.Pivoted bebween the two standards B is the double hood D, which hus its 10w01 end t0 1nove free1y backand forbh over the ventilating hole 0r window I, which is made in the side 0f Ehe Gilt. 'lhis hood, being left free t0 move ab its inner end, has itsinner end shifted back und forth over the ventilating-hole by the pressure 0f Ehe wind fr0m the direction in which the cm is moving. TW0 hoods, which have their upper ends extenc'ling in opposite directions, are connected together, and each hood has an opening through its immer end, which is separate and distinct f10111 Ehe other h0od. \Vheu Ehe cm begins t0 move in any one direction, the pressure 0f the air against the 1100d. whimh is turned in the direction which the car ie moving causes the inner end of the 110001 t0 move direct1y over the venbilaing hole or window in the side of the car, a11d bhen the air which is caught by the hood is forced 1'11t0 the ear. 111 this manner lahe immer ends 0f the hoods are shifted back and forth over the opening 01 window, according t0 the direeti0n in which the cars are made 130 move. The fresh air which is foreed int0 the car may eibher be discharged freely into the cum, 01 pipes may be connected 1t0 the 0pening 01 window, so as t0 conduet the 2Lil to any point that; may be desired. During the winber season these pipes may be conneeted di reet1y t0 the heater, und thus be 1nade t0 0011- ducl; the fresh air 110 t.he heater to be warmed 6 5 before it1 1's discharged in'u0 the car. Fresh air being constantly foreed into the ear ab the top Will cause the f0u1 (LiI' 60 be f0rced out, smd thus keep the ntmosphere. 0f the ein a1- ways pure.

The' standards 01 frmn0-work 1nny be made 0f any s uitable metal, While the hoods will be made 0f any suitahle sheet metal, 0r other material that; may be preferred.

Having thus described our invention, we 01aim* 1. A double hood, in combination wih a suitable frame-work, in which 1't is pivoted, zmd the 02u provided with a suitatble opening 01 window, 130 which the ventilatoris applied, subsbantially es shown.

2. The combination 01." a doublehood, which ispivoted ab 1'ts upper end, und which has its inne1 end t0 move freely back und f01bh over an opening in Ehe side of the am, With the fmme in whieh the hood is pivobed, and which iS provided with st0ps t0 lin1it the movement of the free end 01" the ventilator, substantially as sei: forbh.

In testimony whereof we affix our signatures in presence 0f tw0 witnesses.
